Simulation technologies used in medical education

• Computer-based simulations (micro-worlds,
  micro-simulation)
• Virtual environments /- haptics
• Part-task trainers
• Low-fidelity simulators/manikins
• Simulated or standardised patients
• Hybrid simulations
• High-fidelity (full mission) simulation

9
Knowledge/Skills/Attitudes

• Individual psychomotor skills
• Appropriate application of skills
• Communication / Team performance / Leadership
  skills (CRM)
• Supervision/teaching
• Assessment

10
Knowledge/Skills/Attitudes

• Teaching best practice
• learner centred
• appropriate use of technology
• Assessment best practice
• Valid and reliable
• Reproducible

11
The Flinders Clinical Skills and Simulation Unit

• Grew from a project to improve airway management
  teaching to medical students
• Value to teaching other health professionals and
  other skills recognised
• Funding generated from teaching outside the
  medical school

12
Endotracheal intubation

• Learnt on patients under anaesthesia
• No special consent
• Duty of care to protect patient from harm
• Increased risk when performed by a student or
  trainee

13
Endotracheal intubation

• ETI needed by many health professionals,
  including anesthesiologists, paramedics/EMTs,
  rural GPs, emergency physicians, ICU staff,
  respiratory therapists, etc.
• Competence requires practise

14
When and how should ETI be taught?

• Animals
• Small, e.g. cats
• Large, e.g. dogs or monkeys
• Unconscious patients
• In the OR
• In ICU
• Newly dead/recently deceased
• Cadavers
• Simulators

15
The learning environment

• Quiet, few distractors
• Clinical equipment
• Expert tutors
• Realistic models
• Many different models
• Easy ? difficult? very difficult

19
Anatomy of a simulation (1)

• Components
• Student/trainee/health professional
• Procedure/task/skill/test/treatment or equipment
• Patient and/or disease process
• Trainer/supervisor

20
Anatomy of a simulation (2)

• Function of components
• Passive
• Enhance setting for realism
• Active
• Change in a programmed way
• Interactive
• Responds to action or event

21

• Trainees learning cricothyrotomy on a part-task
  trainer
• (Note educational aids in background)

• Trainee performing an emergency cricothyrotomy in
  a full-mission simulation.
• (Note more realistic setting)

22
High fidelity simulation (1)

• Determine educational needs and choose most
  efficient and effective
• Need to balance resource availability and student
  demand
• May need to promote low-tech solutions

23
High fidelity simulation (2)

• Confirm teaching goals can be achieved using
  simulation
• Develop scenario, acquire equipment needed and
  prepare associated materials
• Test and validate the simulation

24
Options for running simulations

• Free-form
• Easy but poor learning
• On the fly
• Scripted but intensive for the controller and
  some variables may appear discontinuous
• Programmed trends
• More sophisticated simulations possible
• Trends and event handlers
• Facilitates high-fidelity simulation with most
  realistic response to interventions

25
Resources needed

• Equipment
• Simulators, monitors, defibrillator, trolleys,
  etc
• Disposables
• Appropriate for scenario, setting and
  participants, re-use w/o compromising fidelity
• Faculty
• Trained, available, practised
• Support staff
• Technician/bio-medical engineer essential!

26
Before and after simulations...

• Set-up scenario
• eg. make blood, set up area, X-rays, notes, etc
• Load simulation program
• Check everything works
• Cameras, VCR, communicators
• Afterwards...
• Check simulator (replace or repair parts)
• Clean everything used and put away
• Replace/reorder all used items

27
High fidelity simulation (3)

• Allow time for briefing and familiarisation with
  the patient simulator and equipment
• Brief participants on
• Broad objectives
• The scenario
• How to get help

28
High fidelity simulation (4)

• Always follow the script but...

have alternative outcomes planned and rehearsed
Simulation control room
29
High fidelity simulation (5)

• Using simulation situations can be re-run to
  explore outcome with different treatments

Mission critical tasks can be performed by
learners without putting patients at risk
30
High fidelity simulation (6)

• Facilitated debriefing with an expert
  practitioner. Participants reflect on their own
  performance and discuss this with the group

31

• Regional hospitals, rural settings, etc

32
Medicine A High-Risk Industry

• Harvard Medical Practice Study (1991) identified
  a serious error rate of 3.7
• (serious error leads to prolonged hospital stay
  or disability)
• Vincent (2001) NHS 11 error rate with 50
  preventable
• 50,000 patients pa die from medical error or
  accident. Litigation cost 44billion
• Australian data - adverse event rate of 17

33
Successful strategies for crisis management

• Use of written checklists to help prevent crises
• Use of established procedures in responding to
  crises
• Training in decision making and resource
  co-ordination
• Systematic practise in handling crises including
  part-task trainers and full-mission realistic
  simulation

34
The future of simulation...

• Skills training tool for all disciplines
• Acute care
• Try new techniques and/or equipment
• Patient safety initiatives
• Retraining
• Multi-disciplinary training
• inter-professional communication
• team performance
• Training in decision-making/resource co-ordination

35
Simulation technologies used in medical education

• Computer-based simulations (micro-worlds,
  micro-simulation)
• Virtual environments /- haptics
• Part-task trainers
• Low-fidelity simulators/manikins
• Simulated or standardised patients
• Hybrid simulations
• High-fidelity (full mission) simulation

36
Simulation research must address healthcare
training needs

• Improved outcomes
• Fewer adverse events, fewer preventable
  incidents, fewer near miss events
• Increased efficiency of training
• Improved outcomes in same or (preferably) less
  training time
• Improved use of resources
• Fewer failures, more efficient training, quicker
  performance
